Fix CI warnings: update platform version compatibility and resolve Kotlin deprecations

[Copilot]

The CI build was failing with 13 compilation warnings related to platform version mismatch, experimental coroutines API usage, deprecated Kotlin methods, and parameter naming. Additionally, a plugin compatibility issue was causing the plugin to fail loading.

Changes

• gradle.properties: Updated pluginSinceBuild from 213.* to 221 (without wildcard) to properly support IntelliJ Platform 2022.1+ and ensure compatibility with specific builds like IC-221.5080.210
• Experimental coroutines: Added @OptIn(ExperimentalCoroutinesApi::class) to 4 classes implementing coroutines-based interfaces
• Deprecated methods: Replaced toLowerCase() → lowercase() in 2 files (3 occurrences)
• Parameter naming: Changed equals(obj: Any?) → equals(other: Any?) to match supertype signature

Example of coroutines opt-in fix:

@OptIn(ExperimentalCoroutinesApi::class)
class CasbinDocumentManager(private val project: Project) : CasbinDocumentService() {
    override fun processChange(change: CasbinDocumentRequest) {
        // Implementation using experimental coroutines API
    }
}

The key fix for the plugin loading issue was removing the wildcard from 221.* and using just 221, which properly indicates "build 221 or newer" and is compatible with all 221.x builds.

Fixed the plugin compatibility issue in commit f5941a4. Changed pluginSinceBuild from 221.* to 221 (without wildcard). The wildcard was causing the plugin to be incompatible with IC-221.5080.210. Now it correctly supports all 221.x builds.
